Include IPv6 into Cloudron

[imc67]

@nebulon I’ve setup AAAA records manually for all domains, however AAAA for the mailserver doesn’t work. Check your domain and email at https://en.internet.nl and try to get 100%.

For all domains I get a 100% now because you guys did some tweaking in the latest version. However email is still stuck at 84% because of IPv6 and DANE.

It’s now closer to 2022 and really time to implement IPv6 also in blocklists and firewall.

I've run into this recently as well. While setting the records manually would work, automating this (particularly with Cloudflare) would be wonderful.

IPv4 is now double the price as 2020, from 20/25 for 1 IP now is 45/50 for 1 IP.
This is really hard to sustain for those who have their own platform, IPv6 will be really appreciated.

[nebulon]

I guess we can move gradually to support both better in parallel first, for example we could setup AAAA records automatically if a non manual DNS backend is configured. Also not sure what is required for other things like the mail server to bind to that interface as well. Not sure how things like PTR for mail delivery deal with this and if there is an IPv6 equivalent.

IPv6 only Cloudrons are likely a bit harder to get done, but maybe in the future.

[MooCloud_Matt]

A gradual approach is the best, and yes PTR is available for IPv6.
Cloudron can also take advantage of IPv6 "Subnet", and having a dedicated IPv6 for every container.

@girish @nebulon one year later: it’s almost 2022 and still Cloudron is not able to handle IPv6 properly out of the box!?

@nebulon Since ipv4 addresses are getting more expensive it might be worthwhile to start considering and planning for ipv6.

For everyone like myself who still needs to freshen up on IPv6 here a free course by ripe.net

Fair enough, I will add this to 7.1 roadmap I can't promise this gets done though, since we have to investigate what needs to be done. It also depends on services like Lets Encrypt supporting IPv6 nicely (which I think they do by now).

[A Former User]

For those using Hetzner, it seems that they have released IPv6-only versions for some of their dedicated servers. These IPv6-only servers are cheaper since the price of the IPv4 address is deducted from the original price.

More info can be found here https://docs.hetzner.com/robot/dedicated-server/ip/faq-primary-ipv4/.

They are apparently working on IPv6-only cloud servers as well, so it's something to look forward to if Cloudron can support IPv6.

@thpuffin yup, working on ipv6 support for 7.1!
